Substantially right angular sealing clips 4 are disposed atthe ends of the members 2 and have their ends 5 closing the ends of themembers, while their ends 6 are secured by means of screws 7 to thewindows. Curved late springs 8 are disposed within the U- aped membersand have their free ends bearing against the bottomforming portions ofthe members and are secured in position by means of bolts 9 which latterextend through openings provided therefor in the central ortlons of thesprings. The bolts pass throng the side stiles of the window andhavetheiriheadsexposed eas to be ,readily" accessible {for purpose, of.adjustinentof thetension of the springs.

I v l f From the. foregoing itwilhbe.seen that the sidesiofr the; members 10 are iree .for rfiexing movement,dueto the. central securement of the members. As depictedin the".drawings,

the-bases of. the UshapedmembersQ are normally. spaeedjfrom. thebottomsofthe grooves 1,,andare under thetension ofthe springs 8 which.latter act, to draw. the. members 2 and therebytheinflanges or wings3"against. the inturnedsides 12. of the. menibers-1O. .Thus the twbmembersare held inder constant tension and hence in efrictional enggement, which Zlatterfis of such nature or; degree'.to maintain the.windows against vertical.move.- mentinany. position thereof;.- s V Itwill efurthenbe. apparent-that a'complete .sealxisprovided. against the:ingress of air or moisture by virtue of the two members. In this regard,it will be seen that the packing strip positively prevents passage ofair etc., while the interengagement of the parts 3 and 12 a'nd'theaction of the spring in holding the parts 12 against the side edges ofthe window, due to the spring forcing the parts 3 against parts 12, airetc., is likewise prevented from passlng.

Additional fasteners 17 may be provided for the members 2 if desired andwlnch act as guides'for the same as shown in Fig. 3.

What is claimed is 1. In combination with a Window having a groove inits side edge and a casing having a wmclow guide, a substantiallyU-shaped member 111 said groove havlng outwardly extending flangesdisposed over and spaced from the said side edge of the window, curvedplate springs in the U-shaped member havin its free edges bearingagainst the bottom or the member, bolts extending through the springsand member and through the window sides so as to be accessible foradjustment, a member having a base engaged with the bottom of the guideand having inturned sides, said flanges of the first member beingreceived between the base and inturned sides of the second member, saidsecond member having a central longitudinal hollow inwardly extendingbead, a. packing strip in the bead engagedwith the bottom of the guide,and fasteners extending through the bead and into the casing.

In combination with a window having a groove in its side edge and a'asing having a window guide, a substantially U-shaped member in saidgroove having outwardly extending flanges disposed over and spaced fromthe said side edge of the window, spring means to secure said member tothe window and to urge the same toward the member, a member having abase engaged with the bottom of the guide and having inturned sides,said flanges of the first member being received between the base andinturned sides of the second member, said second member having a centrallongitudinal hollow inwardly extending head, a packing strip in the beadengaged with the bottom of the guide, and fasteners extending throughthe bead and into the casing.

3. In combination with a. window having a groove in its side edge and acasing havin a window guide, a substantially U-shaped member in saidgroove having outwardly extending flanges disposed over and spaced fromthe said side edge of the window, a second member having a base securedto the bottom of the guide and having inturned sides, said flanges ofthe first member being received between the base and inturned sides ofthe second member, and spring means to tension the first member to urgesame toward the window thereby to press the flanges of the first memberagainst the inturned sides of the second member.

1. In combination with a window having a groove in its side edge and acasing having a window guide, a substantially U-shaped member in saidgroove having outwardly extending flanges disposed over and spaced fromthe said side edge of the window, a second member having a base securedto the bottom of the guide and having inturned sides, said flanges ofthe first member being received between the base and inturned sides ofthe second member, spring means to tension the first member to urge sametoward the window thereliiy to press the flanges ol' the lirst memberagainst the inturned sides of the second member, and means to secure thebase of the second member to the bottom of the guide disposed centrallyof the width of the second member so as to leave the sides of the baseand the inturned portions thereof tree for flexing movements.

5. In combination with a window and its guide, a member having a baseand inturned sides, means to secure the base to the guide so as to leavethe inturned sides thereof free for flexing movements, said windowhaving a grooved side edge, a second member in the groove havingportions disposed without the groove and received between said base andthe inturned sides of the first member, and spring means in the roove totension the second member thereby to hold its said portions against theinturned sides of the first member.

6. In combination with a window and its guide, a member secured to theguide, said window having a groove in its outer side edge, a secondmember, said members having slidable interengaging portions, means inthe groove to tension the second member thereby to hold saidinter-engaging means under tension, and means operable from the innerside edge of the window to adjust the tension of said tensioning means.

In testimony whereof I aflix my signature.
